Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The number of species has mixed, depending on how they are categorized, thanks to similarity between hybridization and varieties. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is anonymous, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released in to the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as cut plants so that as ornamental plant life in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the icon of cancer charities in many countries. The appearance of the untamed flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The plant stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The blooms, which are conspicuous and white or yellowish usually, sometimes both or seldom green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and flower stem die back again and has contractile root base that yank it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer months to later winter, flowering in the spring, though a few varieties are fall flowering.
